DA Series Air Flow type Alpha-Beta Low-Level Counter

DA Series Air Flow type Alpha-Beta Low-Level Counter

Product introduction

DA series (1-8 channels) Low-Level α/β Counter is a precision instrument for measuring low-level α, β radioactive intensity. It can be used for the measurement of total α and total β radioactivity in water, soil, building materials, ores, aerosols, food, cetc. It is suitable for the measurement of low-level α/β radioactivity in radiation protection, environmental protection departments, medical, biological, agricultural, scientific research institutes and colleges and universities. The instrument is a series of products with 4 models and specifications: DA-101, DA-102, DA-104, DA-108. The instrument meets the verification requirements of JJG1100-2014 air flow proportional counter total α and total β measuring instrument.

Features

• Low background count, high particle detection efficiency;

• The thin-window gas-flow proportional counter tube is used as a detector, and the counter coincidence between the shielded counter tube and the measurement counter tube is used to reduce the interference of radioactivity in the surrounding environment on the measurement;

• The detection efficiency of 14C low-energy β-rays is ≥40%; it is better than similar detectors with semiconductors and scintillators as probes.

• The mass thickness of the gas flow proportional counter tube window is ~2μg/cm-2, the area of the measurement window is Ø60mm, and the sample area is Ø55mm.

• With PC application software, parameters such as high voltage and threshold can be set on the PC side. Simple operation interface, each channel can work and calculate independently; can directly obtain the radioactive specific activity Bq/L or Bq/Kg of the measured sample.
